Application filed May 16, 1913. Serial No. 768,027;

To all whom it may concern Be itknown that I, JAMES Mnnnonrr, acitizen of the United States, residing at Sharon, in the county of Mercer and State of Pennsylvania, have invented certain new and usefulImprovements in Water-Heating Systems, of which the following is a specification.

My invention relatesto improvements in ressure re ulators for hot water heatin b 3 systems. p

In hot water heating systems, it is necessary to maintain all of the circulation pipes During the operation of the system unavoidable leakinthe valves and at points where the pipe fittings connect. For that reason, it is essential to provide a constant supply of water which may be" automatically passed into the system to replace that which has left it. In accomplishing the latter, how ever, it is necessaryto prevent the passage of the hot water from the system back into the reservoir, in that, satisfactory water temperature can only be maintained under pressure.

In the present invention, my purpose is the construction of such a system as will permit of all the usual functionsof a hot water circulating system and at the same time, permit of the water being maintained at a much higher pressure, and consequently, at a much higher temperaturethan has heretofore been obtained. This result has been obtained by the employment, of structure and arrangement of partssuch as that shown in the accompanying drawings In the drawing, Figure 1 is aside elevation of a portion. of a hot water circulating system, showing the connection between the water reservoir and the system, supply, a portion of the structure therein shown beits being more readily understood. Fig. 2 is-a side elevation of the water reservoir with the condenser and waste pipe connected thereto.

Referring now to these drawings, A is a cylindrical chamber; B achamber of similar design, but substantially larger in capacity. Connecting the bottom of these two chambers is an inverted gooseneck tube C,

the ends ofwhich are open and extend up into the chambers A and B respectively. At the bottom of each chamber, the tube is provided i a nu'mber of small holes,

E and EC, Positioned near the top of each chamber and extending over the ends of a the tube are the bafiies F-F. Connecting the upper portion ofthese two chambers are the pipesv and fittings G G,- interpos1t1o-ned in which is thecheck valveHso set as to prevent a passage of waterfrom the small into the large chamber] Small openings provided With' suitable closures, KK are-provided ,at'the bottom of each of the-two chambers, wherebygaccess is as forded to each of thesetw'o chambers for the purpose of cleanin'g,.etc. I k

The pipe A connects the smaller chains her with the hot water circulating system.v Extending upwardly from the top of the open top member LTconnected to the top thereof, L is shown in outlinepositioned within the collar M, at the lower part of which collar is an outlet provided with a.

chamber B, is "a fitting L having aconical suitableclosure M. Connected to the top of the collar M is the pipe N, which isconnected to the T N; Extending horizontally '80 'froinT N is the pipe 0, hand valve P and the pipe It leading to theinitial water. supply. [Extending upward from the T N .is

the pipe S leadingto the water reservoirtT,

this water reservoir havingthewater gage N thereon. Extending from the top'oflthe ,reservoir is the pipe U leading, into the 6X pension chamberV. Connecting to the top of this chamber is a T from the upper portion. of whichextends the air vent X' and from the side of which it extends vthe wast-e pipe Y. s i

Whenmy upper ends L, G and H, where the valve swingmgto the right permits it to pass into the pipes G,

device is in operation. the tube C is supplied with a mercury column. D

top of the chamber. A and on through A into the circulation pipes. In itspassage into the a member M dirt and sediment will be collected by the trap L and at suitable intervals can be removed therefrom by removal of the closure M. It must of course be understood, that this apparatus, in common 5 with all others now in the market, ispositioned in the attic where the water will normally flow into the system by gravity. The pipe now being filled and the pressure having risen to an abnormal degree, the water in expanding is prevented from passing directly into the chamber B on account of the check valve H. All of the pressure is therefore exerted against that end of the mercury column below the chamber A, and as the pressure increases that end of the column is depressed and the end leading into chamber B correspondingly raised. hen eventually the pressure becomes too strong, the mercury is forced out through the top of the tube G into the chamber B, where it may under great pressure strike the battle F and be thrown down against the bottom of the chamber. The mercury will then drain slowly through the holes E back into the hole C. The purpose of preventing its rapid -passage back into this tube is to eliminate any air pockets therefrom. Under a sudden reduction of pressure, should the mercury pass rapidly back into the chamber A, the action of the mercury will be exactly similar as to that in chamber B.

l Vhen the gage shows that the water is low in the reservoir T, the hand valve is opened to admit of fresh water direct. If, under extreme rise in the pressure, the hot water is forced up into the reservoir T, any

steam condensed in the chamber V is returned to the system, while any undue overflow is taken care of by the overflow 40 which leadsinto the sewer or some drainage. 3

From the foregoing description, it must be realized that I have provided means for supplying the system with water which is not interfered with by any mercury column orwell, and when there is sufficient water, while at all times preserving safety, the full resistane of a mercury column is opposed to the heated water. By the employment of my system, I have been enabled to use pipes of as small diameter as g, and maintain a temperature as high as 258.

I claim,

suitable 1. In a water heating system, thecombination of two chambers, a U-shaped pipe connecting thebottoms of said chambers and having .a mercury column second pipe leading 4 from the top of one chamber to the top of the other and having .bers and terminating below forat-ions in both ends of pipe Y valve, one of said chambers therein, and a therein means for preventing the passage of water therethrough in one direction only.

2. In a water heating system, the combination of two chambers, a pipe having its ends entering and extending above the bottoms of said chambers, perforations in each end adjacent said bottoms, a second pipe, having a check valve therein, connecting said chambers and means in said first pipe opposing the flow of water therethrough, as, and for the purpose, set forth.

3. In a water heating system, the combination of two chambers, a battle plate in each chamber, a pipe, having a check valve therein, entering said chambers above the baifie and a second pipe, located exteriorly of the chamber and having a mercury column therein, entering, and extending above the bottom of said chambers, said second pipe having its ends perforated above and adjacent the bottoms of the chambers.

4. In a water heating system the combination of two chambers, bailles located at the upper end of each chamber, a pipe having a check valve therein connecting the tops of said chambers, a U shaped pipe entering and extending above the bottom of said chamthe battles, perthe latter pipe, said perforations being flush with the bottom of the interior of the chambers, and a mercury column within said latter pipe, as and for the purposes set forth.

5. In a water heating system, the combination of two chambers, baiiies therein, two pipes exteriorly located connecting said chambers, one of said pipes containing a mercury column which is normally free from both chambers, and the other a check connecting directly with the main system and an expansion tank connecting with the other chamber.

6. In a water heating system the combination of two chambers, two pipes connecting the same, one of said pipes containing a mercury column, VhlCll is normally below the bottom of both chambers, and the other a check valve, a source of water supply, a trap between the latter and one of said chambers, an expansion tank, a reservoir connected thereto, and pipes connecting said reservoir and trap.

In testimony whereof I aflix my signature in presence of two witnesses.
